Patient's question:
Over a year ago, menstruation was intermittent within a month, lasting for about half a month. The color was dark red with blood clots. Recently, I went to the local hospital for an ultrasound.Doctor's answer:
Hello, according to your description, it is a normal phenomenon for menstruation to be affected by external factors and occur about a week earlier or later. Menstruation is the regular shedding of the endometrium under the influence of hormonal levels in the body. It is recommended to thoroughly examine the cause.
